BRAKE-BLOCK.

SPECIFICATION forming part of Letters Patent No. 317,177, dated May 5,1885.

Application filed December 29, 1884. (N 0 model.)

To all whom it may concern.-

Be it known that I, H. G. NE TON, of Groton, in the county of Tompkinsand State of New York, have invented certain new and useful Improvementsin Brake-Blocks for Vehicles; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawing,which forms part ofthis specification.

My invention relates to an improvement in brake-blocks for vehicles; andit consists in the combination of a metallic frame, the slotted block orcore that is placed therein, the brakerod which passes through the frameand the core, and a set-screw for adjusting the block, as will be morefully described hereinafter.

The object of my invention is to provide a means for adjusting the blockin the frame for the purpose of clamping the leather or rubber inposition between the block andthe frame.

The accompanying drawing represents a cross-section of a brake-blockembodying my invention.

A representsa brake-block,which is preferably made crank-shaped at eachend, and which is provided with a shoulder, H, which acts as a stop forthe frame, and with a nut, G, upon its end for the purpose of clampingthe frame between the nut and the shoulder,

and thus securing it in place upon the rod.

The frame B may either be of the shape here shown or any other that maybe preferred, and which has formed upon its open side suitable shouldersor flanges,I, for catching against the leather or rubber D.

Inside of the frame B is placed the block or core 0, which has asuitable slot made through it for the end of the rod A to pass through,0 and which is enough smaller than the frame to allow the block amovement back and forth therein for the purpose of allowing the rubberor leather 1) to be removed, or replaced, or adjusted at any time. Uponeach side of this, 5 core or block are formed suitable shoulders tocorrespond with the shoulders I on the frame B, and in between theshoulders on the block and the shoulders on the frame the edges of theleather or rubber are held.

Passing through the frame B is a set-screw, E, which bears against theinner side of the block B, and which screw serves to hold the block inany desired position. By turning the screw in one direction, the block 0can be forced tightly against the shoulders I, and thus clamp the rubberor leather securely in place, and, when turned in the oppositedirection, its pressure is withdrawn from the block 0,

and thus the block can be moved baokin the 50 frame, so as to releasetherubber or leather D. The block being slotted, as shown, it has afreemovement upon the end of the red A.

Having thus described my invention, I claim- The combination of thebrake-rod with the frame B, the block 0, having a suitable slot throughit for the end of the rod to pass through, and the set-screw for holdingthe block in position, the frame B being provided with shoulders I,substantially as described.

In testimony whereof I affiX my signature in presence. of two witnesses.

HERBERT O. NEWTON.
